EIP-8

[fjl]

Implements ethereum/EIPs#49.

[fjl]

@ms83 I can't get full app tests to pass (see Travis output in this PR). Do they pass for you?

[panpilkarz]

Yes. https://travis-ci.org/ethereum/pydevp2p/pull_requests

[fjl]

Alright. We've decided to go forward with EIP-8, so this PR is now open for review.

I still can't get the full app tests to pass. I tried cherry picking the first few commits from #35 but it didn't help.

[fjl]

Rebased again. Tests work now (thanks @ulope).

You can test the RLPx handshake changes against go-ethereum by doing:

... start your node...

git clone --branch develop https://github.com/ethereum/go-ethereum
cd go-ethereum
make
RLPX_EIP8=yes ./build/bin/geth --bootnodes <your enode URL>
